Yard issue. Just dont know what to do

[Tinypony]

I asked OP ages back how big the stables are in the barn. The reason for that was that it sounds as if they are quite small, that might be why nobody wants to go in there? If a "big horse" can hardly turn around, then that sounds like pretty small stables to me.
I see no point in continuing to occupy someone else's stable. When she gets back she's going to be rightly upset, you could end up getting chucked off anyway. So deal with the situation now.

I think you've had some very good advice here.
